PATENTEU 19 I97? 3. 706 690 sum 1 OF 7 PATENTED nEc 19 m2 SHEET 2 0F 7LATl-IER MAKING APPARATUS BACKGROUND OF THE INVENTION The invention isconcerned with lather making apparatus which is adapted to automaticallyproduce lather utilizing conventional bar or cake soap. The lather issuited for use either in connection with shaving or for general washingpurposes as in washing the hands and face. In order to produce thelather, it is necessary to engage the bar of soap with mechanical meansfor mixing the soap with water and air. In the instant apparatus, abrush is employed as the mechanical means for converting the bar soapinto lather. The water combined with the action of the brush against thecake of soap produces a lather for the purposes mentioned above.

Since it is relatively simple to create lather for washing purposes bymerely rubbing ones hands against a bar of soap in the presence ofwater, any appliance which is to be sold successfully to perform thisfunction must be simple, inexpensive, and provide significant functionaladvantages over the manual methods available. In addition, the appliancemust be completely safe to eliminate any hazards which otherwise mightbe involved in the use of an electrical appliance around water in thebathroom or kitchen.

Examples of prior art lather making machines of this general type areshown in the patents to Wahl US. Pat. No. 2,3l0,378, Wahl US. Pat. No.2,310,379, Rolstad et al. US. Pat. No. 2,344,170, and Rolstad No.2,919,837. All of these patents disclose motor driven lather makingdevices which utilize cake or bar soap and generate lather in a chamberby rotating a sponge or brush against the soap while in the presence ofwater. A reservoir is provided to contain the water which is dispensedinto the lather generating area at the same time the brush is rotated bythe motor. The prior art devices as characterized by these patentswere-complex structurally and were deficient from functional and safetystandpoints.

SUMMARY OF THE INVENTION The present invention comprises a lather makingappliance in which the motor, the lather generating chamber, and thewater reservoir have been integrated together to provide a simple,compact, and efficient device for generating a dry lather in a minimumperiod of time. The bar soap receiving compartment is positioned withinthe water reservoir which is nested against the lather generatingchamber to provide an efficient arrangement wherein the water and soapmay be readily dispensed into the lather generating chamber.

The lather generating chamber itself is a generally cylindricalcompartment extending horizontally and enclosing a cylindrical brushhaving the bristles disposed helically. Upon rotation of the brush inengagement with the cake of soap and in the presence of water, lather isgenerated which is driven toward one end of the cylindrical chamber bythe helical configuration or disposition of the bristles. The dischargefrom the lather generating chamber is positioned above the bottom of thechamber and past the bristles disposed within the chamber. The bottom ofthe lather generating chamber slopes away from the lather discharge sothat any water residue remaining in the chamber after lather generationwill tend to accumulate at the end of the chamber remote from thedischarge. Thus, when the device is again started up to produce lather,there will be a generation of lather utilizing the accumulated water,and the water will not be sprayed out the discharge passageway prior tothe building up of good quality lather. Similarly, the spacing of thedischarge beyond the end of the brush prevents the brush from throwingany water particles out through the lather discharge passage.

The water reservoir is heated by means of a distributed electricalelement which is wrapped around the outer wall of the reservoir. Anactuating bar which is positioned below the mouth of the dischargepassageway permits the user to actuate the appliance with the same handwhich is disposed palm upwardly to receive the discharging lather. Theactuator is designed to simultaneously open a valve for discharge ofwater to the lather generating'chamber while actuating a sealed switchwhich closes the motor circuit to rotate the cylindrical brush. Themotor is completely encapsulated as are the electrical connections tothe cord and to the switch so that there would be no shock hazard if theappliance were inadvertently dropped into the sink orbathtub while beingplugged in.

An object of the present invention is to provide improved lather makingapparatus which is simple in design and inexpensive to manufacture.

A further object of the present invention is to provide an improvedlather generator which will produce quickly a light lather having aminimum amount of moisture contained therein and being warm enough foruse in shaving.

An additional object of the present invention is to provide an improvedsoap lather generator which has sealed electrical components toeliminate or minimize shock hazards.

Still another object of the present invention is to provide lathermaking apparatus having a generally upright housing within the upperpart of which is enclosed a water reservoir with a bar soap receivingpassage positioned within the reservoir and a horizontally disposedlather generating chamber extending across the bottom of the reservoirand a motor positioned coaxially with the lather generating chamber toprovide a compact arrangement of the components.

A further object of the present invention is to provide lather makingapparatus having an upright housing with the water reservoir disposed inthe upper portion thereof and a horizontally disposed generating chamberwith a motor secured thereto positioned below the reservoir and a soapreceiving passageway disposed within the reservoir and extendingdownwardly into the lather generating chamber with an open bottomed soapcarrier being telescopically received within the passageway to supportthe bar soap 7 l060ll 0334 BRIEF DESCRIPTION OF THE DRAWINGS For abetter understanding of the present invention, reference may be had tothe accompanying drawings in which:

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawingsthereis shown in FIG. 1 a perspective view of the lather makingapparatus designated generally be reference numeral 11. The apparatus orappliance 11 includes a generally upright housing 12 which is defined bya box-like housing member 13, a rear closure plate 14, and a cover 15.As is best shown in FIG. 4, there is received in the housing member 13 areservoir assembly 17 and a lather generating assembly 19. The lathergenerating assembly 19 includes a horizontally disposed generallycylindrical lather generating chamber 20 and a shaded pole inductionmotor 21. I

The housing member 13 is provided with side walls 13a, a front wall131:, and a pedestal-like base 130. On the front side of the housingmember 13, there is a recess 23 formed by wall portion 13d which curvesinwardly and downwardly from the front wall 13b and interconnects to thepedestal base 130, as is best shown in FIGS. 1 and 2 Positioned withinthe recess 23 is an actuating lever 24 which is depressed in order toenergize the motor 21 and to cause water to flow from the reservoir 17into the lather generating chamber 20 as will be more completelydescribed below. The actuating lever 24 consists-of two parallel barportions 24a which extend through openings 13s in the housing member 13to a point where they are pivotally mounted on the rear of curved wall13d, as is shown in FIG. 2. The bar por-' tions 24a are interconnectedat their ends at the front by a manual push bar 24b and at the rear by atrip bar 240.

In operating the appliance, the user inserts his-hand, palm upwardly,into the recess 23 and exerts a downward pressure on the push bar 24bcausing the actuating lever 24 to pivot whereby the trip 'bar 24c movesupward to cause the lather to be generated. As the lather is generated,it is dischargedfrom a centrally disposed opening 13f which ispositioned immediately above the push bar 24b. Thus, the lather isdischarged into the palm of the hand which simultaneously operatesthe'actuating lever 24.

To accomplish the pivotal mounting of the actuating lever 24, there areprovided integrally molded pivot pins 24d which extend laterally fromeach of the bar portions 240 of the actuating lever. These pivot pins24d are received in slotted trunnions 13g which face rearwardly, asshown in FIG. 4, and trunnions 13h which face forwardly. In order toassemble the actuating lever 24 to the housing member 13, the barportions 24a are inserted from the rear through the openings 13c priorto the assembly of the push bar 240 to the front ends of the barportions 24a. The openings l3e are wide enough so that the bar portions24a may be deflected inwardly to snap the outwardly directed pins intothe forwardly facing trunnions 13h and seated against the rearwardlyfacing trunnions 13g. The push bar 24b is-then cemented to the frontends of the bar portions 24a thereby providing an actuating lever whichis firmly supported on the housing member 13 by means of the engagementof the pivot pins 24d with the trunnions 13g and 13h.

In order to facilitate cleaning up or removing any lather which mightspill over from the palm of the hand during the dispensing operation,there is provided a removable tray 26 which is positioned on thepedestal base 13c and defines the bottom of the-recess 23 as best shownin FIG. 1. The tray 26 is formed with a slight depression 26a so as toreceive and retain any liquid or lather which may be deposited thereon.A small postlike protuberance 26b (see FIG. 2) extending downwardly fromthe rear edge of tray 26 engages opening 13j in housing member 13 forthe purpose of retaining the tray in position with respect tothepedestal base 13c. The tray 26 may be easily removed for cleaning bymerely elevating the tray to disengage the post 26b from the opening 13This permits the tray to be washed thereby maintaining the neat andsanitary appearance of the apparatus 1 1 without having to wash orimmerse the entire housing 12.

The reservoir assembly 17 is designed to store heated water which may bedispensed into thelather generating chamber 20. As is best shown in FIG.4, the reservoir assemblyl'l includes a box-like tank or reservoirmember 28 which is defined by vertically extending side walls 28a whichterminate in a peripheral flange or lip 281;, which rests within theupper end of the housing member 13, as is best shown in FIGS. 5, 6, and7. In order to position the reservoir member 28 within the I060Il 0335housing member 13, there are a plurality of inwardly extending stops13k, as best shown in FIG. 4. The stops 13k engage the underside of thelip or flange 28b on the reservoir member to position the reservoirmember vertically with respect to the housing member 13. Wedge-likemembers 280 on the walls of the reservoir member are formed to engagethe stop members 13k and dovetail into engagement with each other. Thisdovetailed engagement between the stops 13k on the housing member 13 andthe wedge-like members 28c increase the rigidity of the assembledhousing member and reservoir assembly thus restricting the flexure ofthe relatively thin plastic walls of the abutting parts. The reservoirassembly is retained in engagement with the housing member by means ofhook-like projections 28d, best shown in FIGS. 2 and 4, which snap intoengagement with the housing member l3 to prevent upward displacement ofthe reservoir assembly 17. The rearmost one of the projections 28d hooksbeneath a tranversely extending wall or rib 13n extending across theupper portion of the back of the housing member 13, as best shown inFIG. 4. The forwarding located projection 28d merely hooks into a recessin the front wall 13b of the housing member 13.

As a means of increasing the rigidity of the reservoir member 28, thereis provided a removable wall member 29 shown in FIGS. 4 and 7. The wallmember 29 is supported in the reservoir member by means of spaced ribs28e which receive the wall member 29 when it is inserted from the top.The lower corners of wall member 29 are cut away so that liquid may flowthrough wall member 29 to either side of the reservoir.

Located within the reservoir member 28 is a vertically extending soappassageway 30 which is defined by transversely extending front and rearwalls 31 and 32, respectively, a connecting wall 3, and a secondconnecting wall 34 which is essentially common with one of the sidewalls 28a of the reservoir member as is shown in FIGS. 4, 7 and 8. Atthe lower end of the soap passageway 30, the walls 31, 32, and 33 areconnected to the side walls 28a by the bottom wall 28f. This provides awater containing area which is defined by the side walls 28a, the soappassageway walls 31, 32, 33 and the bottom wall 28f. The soap passageway30 is completely enclosed by the water containing portion of thereservoir except, of course, at the wall 34 which is common with one ofthe side walls 28a.

The soap passageway 30 is made of sufficient cross section and length toaccommodate any conventional bath size bar or cake soap. In order tofacilitate insertion and removal of the soap as well as to permitutilization of smaller pieces and chips of bar soap, a soap basket 35 isutilized. The soap basket, as shown in FIGS. 2, 4, and 8, has side walls35a'and a lifting ledge 35b. The cross section of the basket 35, asdefined by the side walls 35a, is such as to be snugly received withinthe passageway 30, as shown in FIGS. 2, 5, and 7. When the basket isreceived within the soap passageway 30, the lower edges of the sidewalls 350 engage the lather generating assembly 19 with the upper edgesof the basket substantially flush with the flange 28b on the reservoirmember. The lifting ledge 35b extends laterally of the side walls 35aand permits the user to lift the basket 35 out of the passageway 30 toremove soap or for cleaning purposes.

To provide means for supporting soap in proper position for engagementby the lather generating means, the soap basket 35 is formed with aseries of spaced ribs 35c which extend across the shorter dimension ofthe passageway formed within the side walls 35a. The ribs 35c, as shownin FIG. 2, are curved for reasons which will be more completelydescribed below.

In order to heat the water contained within the reservoir member 28, anelectrically energized, distributed heater 36 is secured against theside walls 28a of the reservoir member as shown in FIGS. 3 and 4. Theheater 36 consists of printed or impregnated carbon on an asbestos back.The carbon and asbestos is then sandwiched between mylar andpolyethylene to provide a sheet which may be energized at sealedterminals 37 to heat the contents of the reservoir member 28. The heater36 in the disclosed embodiment extends around three side walls of thereservoir member 28 and may be secured to the side walls by means of anysuitable adhesive and/or clips 27 (see FIGS. 3 and 6).

Positioned immediately beneath the reservoir member 28 within thehousing 12 is the lather generating assembly 19 which is best shown inFIG. 4. The lather generating chamber 20 is formed by a cylindricalenclosure 38 within which is received a cylindrical brush member 39. Theend of chamber 20 most remote from motor 21 is closed by means of a cap40 which is secured within the opening 38a to seal the opening againstleakage and which has a recess 40a to receive the free end of the brushmember 39. The outer wall of the cap 40 is formed with a wall 40b whichis received in a slot 13m on housing member 13 to aid in locating andsupporting the lather generating assembly 19 with respect to the housing12. The cap 40 is assembled to enclosure 38 by means of screws 41, asshown in FIG. 6.

At the other end of enclosure 38, there is provided a frame member 42which serves to interconnect the motor 21 and the chamber 20 and, inaddition, serves as a closure for the circular opening 38b formed atthat end of the enclosure 38. The frame member 42 is formed with acylindrical boss 42a shown in FIG. 7 which extends toward the motor 21and engages the motor field. Similarly, another molded projection 42bshown in FIG. 4 extends into engagement with the motor field. Both ofthese projections 42a and 42b threadedly receive assembly screws 43which extend through the field of motor 21 to the frame member 42.

The brush member 39 includes a cylindrical hub portion 44 which issupported on a shaft 45 which, in turn, is coupled to the motor 21. Inorder to minimize leakage-in the area where the shaft 45 extends throughthe frame member 42 into the enclosure 38, the hub portion 44 is formedwith a conical skirt 44a (FIG. 7) which terminates in a rim 44b which,in turn, is received in an annular groove 42c formed in the inner faceof the frame member 42. The skirt 44a, the rim 44b, and the cooperatinggroove 420 form a baffling arrangement which tends to prevent the lathergenerated in the enclosure 38 from leaking outwardly along the shaft 45.

The brush member 39 includes a double helix of bristles 46 which extendoutwardly terminating at the side walls of the enclosure 38. At theupper portion of the enclosure 38, there is provided a rectangularopening I060Il 0336 38c (FIG. 4) into which the lower end of the soapbasket 35 extends. Shoulders within the opening 380 receive and supportthe lower ends of the side walls 35a. This positions the soap supportedon the ribs 350 within the opening 38c of the lather generating chamber.The bristles 46 are made of sufficient length that they extend betweenthe ribs 35c into engagement with the soap supported thereon as shownsin FIG. 2. Thus, as the motor 21 rotates the brush member 39 within theenclosure 38, the bristles 46 engage the soap and tend to break awayportions thereof which, when combined with water and air, producelather.

In order to supply water fromv the reservoir member 28 into theenclosure 38, there is formed a valve 48 which is formed in part by thereservoir member 28 and in part by the cylindrical enclosure 38. As isbest shown in FIGS. 4 and 5, the reservoir member 28 is formed 5 and 8)which permits the member to be adjustably positioned with respect to thethreaded opening 28h. The lower end of the metering member 49 is formedwith a tapered slot 49b (FIG; 5). The amount of threaded engagementbetween the metering member 49 and the opening 28h determines the rateof flow of liquid from the reservoir member 28 into the enclosure 38. Byadjustment of the member 49, the composition of the lather may be variedfrom wet to dry depending on the rate of water flow to the enclosure 38.

For the purpose of initiating or terminating the flow through theopening 28h, the valve 48 is further provided with a reciprocating valvemember 50 which is mounted for vertical sliding movement within a hole38d formed in a cylindrical boss 38c which extends from the rear wall ofthe enclosure 38 (FIGS. 4 and 5). The upper end of the cylindrical boss38c receives the downwardly depending extension 28g to form the valvehousing 51. The valve member 50 is formed with an enlarged sealingportion 50a which is spring biased by spring 52 into engagement withvalve seat 53. Integrally formed with the enclosure 38 is ahorizontallyextending passageway 38f which connects with the hole 38d to permitwater to flow from the valve housing 51 into the interior of theenclosure 38. At the bottom of the cylindrical boss 38e, there isprovided a flexible rubber boot 54 which is sealed to the lower end ofthe boss 38c and 24c of the actuating lever 24 so that upon depressionof the push bar 24b the valve member 50 is raised thereby permittingwater to flow through the valve housing 51 through opening 38f and intothe cylindrical interior of the enclosure 38.

As water, soap, and air combine to produce lather within the enclosure38, brush member 39 is rotated in the direction shown by the arrow inFIG. 7 (counterclockwise as seen in FIGS. 2 and 5) so that the helicalarrangement of the bristles 46 causes the lather to move from right toleft, as viewed in FIG. 7. The frame member 42 is formed with an annularpassageway or channel 42d which commences at a point toward the rear ofthe enclosure 38 adjacent the projection 42b and gradually increases indepth until its maximum depth whichis toward the front of the housing ata level corresponding to the axis of shaft 45 (FIG. 11). FIG. 11, whichis a sectional view through the frame member 42 taken along line 11-11of FIG. 10, illustrates clearly the manner in which the channel 42d in-.creases in depth toward the forward part of the lather generatingchamber. As the lather is urged toward the frame member 42 by thehelically disposed bristles 46, the lather enters the channel 42d andmoves forwardly past the front wall of the cylindrical enclosure 38, asis evident from FIG. '10. At that point, the channel terminates at asloping wall 42 which urges the lather back toward the front wall of theenclosure 38 where it is directed forwardly and downwardly by the wallof the discharge chute 55. The chute 55 is formed by side wall 383, topwall 38h, and bottom wall 38j formed inte'grally with the enclosure 38(FIG. 9) and also with side wall 42f formed integrally with the framemember 42. Thus, it should be understood that the lather moveslengthwise along the brush member 39 towards the motor while it is beingformedand upon reaching the end of the cylindrical lather generatingchamber it is carried forwardly by the channel 42d formed on framemember 42 and then caused torevers'e direction and move along theoutside of the foam generating chamber and forwardly through thedischarge chute 55. As is evident from FIG. 2, the discharge chute 55 isin alignment with the discharge passage 13f so that the lather willleave the housing 12 at this point and be deposited within the palm ofthe user.

In connection with the generation of lather within chamber 20, it shouldbe noted that the enclosure 38 is formed with lengthwise extending ribs38k, as shown in FIGS. 2 and 7. These ribs tend to create aninterference with the bristles 46 thereby cooperating with the soap andwater to whip up lather in a more efficient manner. In addition, theribs 38k cooperate with the helical configuration of the brush andthereby tend to urge the lather toward the channel 42d and the dischargechute 55.

Positioned at the bottom of the lather generating chamber 20 andadjacent the end toward the motor 21 is an abutment 56 which is formedin part by a shoulder 38m (FIG. 10) and a mating abutment 42g extendinginwardly from the frame member 42. The abutment 56 extends inwardly fromthe end of enclosure 38 only about three-sixteenths of a inch and isintended to engage the endmost bristles 46 and prevent these bristlesfrom throwing water particles out through the discharge chute 55. Theportion 42g of the abutment 56 slopes gradually and merges into thechannel 42d.

To connect the apparatus 11 to a source of electrical power, there isprovided a conventional power cord 57. One side of the power cord 57 isconnected to both the motor 21 and to one terminal 37 of the heater 36.The other side of the power cord 57 is connected to the other heaterterminal 37 and to the motor 21 through a switch 58 which is secured tothe bottom 28f of the reservoir assembly 28 in the position shown inFIG. 3. As illustrated in detail in section in FIG. 12, the switch 58 isa simple, two pole switch which is enclosed within a molded plastic box59 having an opening 59a through which an operating plunger 60 extends.In order to seal the switch against the entrance of moisture, a rubberl060ll 0337 boot 61 is provided. The bdot tightly grips the switch 1actuating plunger 60. Two resilient switch members 62 are mounted withinthe box 59 by means of a bridge. support 63 having a rectangularlocating portion 64 which extends through corresponding openings in theresilient switch members 62. Resilient plastic spacers 65 are alsoreceived on the locating portion 64 to maintain the switch members 62spaced from each other and located within the switch housing 59. Whenthe bridge support 63 is inserted through opening 590 in the switchhousing 59 with the switch members 62 and spacers 65 assembled thereto,it may be slid inwardly until the bridge support 63 engages a shoulderor step 59d. This limits the inward insertion of the assembly includingthe switch members and the bridge support. A quantity of roomtemperature vulcanizing silicone rubber 66 is deposited into the opening59c to complete the sealing of the switch housing 59 and to retain theparts against disassembly therefrom. This provides a simple, compactwater sealed switch which is closed upon upward movement of theactuating plunger 60. 1

In order to guide the actuating plunger 60 for vertical slidingmovement, the frame member 42 is formed with slotted projections 42h, asbest shown in FIG. 4. These slotted or hook-shaped projections receivethe plunger 60 and guide it in its vertical reciprocating movement. Aspositioned in sliding engagement with the projections 42h, the lower endof the plunger 60 rests against the trip bar 240, as shown in FIG. 3.Thus, when the exposed push bar 24b is urged downwardly by the user, theswitch actuating plunger 60 moves upwardly closing the switch 58 andthereby connecting the motor 21 across the power supply. At the sametime the trip bar 240 operatesthe switch 58, it also opens the valve 48allowing water to flow downwardly into the lather generating chamberwhere it is agitated together with the soap by the brush member 39thereby producing lather.

To avoid any possibility of the actuating lever inadvertently operatingthe valve 48 or the switch 58, there is provided a leaf spring 67 (FIG.2) which issupported at one end in a recess in housing member 13 whilethe within the slot 74 which faces upwardly and extends around theopening 380 formed in the top of the lather generating chamber 20 (FIGS.2, 4, 5 and 7). Since the lather within the enclosure 38 has no tendencyto leak out between the junction involving the cylindrical enclosure 38and the reservoir member 28, there is no need to provide a liquid sealin the slot or channel 74. The only seal necessary between the reservoirassembly 17 and the enclosure 38 is within the valve housing 51. Asuitable sealing cement is employed to prevent leakage between thecylindrical extension 28g and the recessed interior of the cylindricalboss 38c. The assemblyof the reservoir 17 and the lather generatingassembly 19 to the housing member 13 is such that there are no criticaldimensions with respect to the fit of the parts. The housing member 13provides the structural support for the assemblies 17 and 19 with theonly interengagement being between the slot 74 and the lower edge of thereservoir assembly 17 as well as in the area of the valve housing 51.This provides a rigid and easily assembled unit wherein the lathergenerating assembly 19 is simply secured in the housing member 13 byscrews in the mounting tab 70, and the reservoir assembly 14 is droppedin from the top with the hook-like projections 28d locking the reservoirmember to the housing member 13.

The housing 12 is formed by the housing member 13 and the rear closureplate 14 which closure plate also serves to hold the lather generatingassembly 19 rigidly within the housing 12. The upper edge of the closureplate 14 is formed with an inwardly stepped ledge or edge 14a whichextends under the transverse wall l3n (FIG. 5). The ledge 14a isinterrupted 'to provide clearance for the stops 13k, the wedge-likemembers 28c, and the projections 28d. The lower'end of the closuremember 14 is formed with an opening 14b which unsupported end engagesthe central portion of the trip bar 240. When hand pressure is appliedto the push bar 24b, the actuating lever 24 is readily pivotedovercoming the biasing function of the spring 57 and actuating the valve48 and the switch 58.

The lather generating assembly 19 is supported upon the housing member13 by means of an L-shaped stamped frame 69 (FIG. 4) which is screwed tothe face of the motor field 21 on the side opposite from the enclosure38. The frame 69 has a front mounting tab 70 which is secured by screwsto the front wall 13b of the housing. The frame 69 is formed with alocating sup port 71 which is received in slot 72 formed in the pedestalor base 130 of the housing. As was previously indicated, the end of thelather generating assembly 19 remote from the motor includes a locatingwall 40b which is received shortly between the walls 13m on the housingmember '13 to locate the lather generator assembly 19.

The reservoir assembly 17 is formed so that the soap passageway 30formed therein has the lower edges of its walls 31, 32, 33, and 34positioned to be received provides access to a cord storage chamber 76.An inwardly directed wall 140 formed integrally with the closure plate14 forms the top of the chamber 76 and prevents the cord stored thereinfrom becoming tangled with the actuating lever 24.

For the purpose of retaining the supporting wall 40b on the lathergenerating assembly 19 seated within the slot 13m, the closure plate 14is formed with an inward projection 14d, as is best shown in FIG. 6. Theprojection 14d engages the wall 40b and wedges it into seated engagementagainst the cooperating portions of the housing member 13. Also to aidin maintaining the lather generating assembly 19 seated against thehousing member 13, the frame 69 is formed with a rearward projection 77shown in FIGS. 3 and 4. The projection 77 engages the closure plate 14thereby urging the frame 69 and the associated support 71 into seatedengagement with the slot 72. To increase the rigidity of the assembly, achannel-shaped projection 14a, shown only in section in FIG. 3, extendsforwardly from the closure plate 14 to receive the projection 77.Assembly screws 78 extend through the lower edges of the closure plate14 to retain it in position with respect to the housing member 13. Toprovide further rigidity between the housing 12 and the lathergenerating assembly 19, the frame 69 is provided with a rear support tab79 which has a pair of threaded openings formed therein. Suitableassembly screws 80 extend through openings in the closure plate 14 intothreaded engagement with the rear support tab 79.

within the reservoir member 28 from condensing within the soappassageway30 where it would tend to soften or liquefy the soap in an undesirablemanner. The cover may, of course, be readily removed to add water to thereservoir member 28 or to remove the soap basket 35 to replenish thesoap supply therein.

In operating the apparatus 11, the cord 57 is connected to a suitablesource of power and water is added to the reservoir member 28. The lowwattage heater 36 causes the water contained in the reservoir to beheated up to a temperature of approximately 100 F. When lather isrequired, the user simply depresses the actuating lever 24 with the palmfacing upwardly beneath the discharge passage 13f. Upon depression ofthe lever 24, thevalve member 50 is forced upwardly as is the switchactuating plunger 60. The actuation of switch 58 causes the motor 21 torotate the brush 46 in engagement with the soap positioned within thebasket 35. At the same the passage 13f. In addition, the abutment 56formed at the bottom edge of the enclosure 38 adjacent the discharge endof the generator tends to provide an obstruction against the bristles 46throwing water or liquid out through the discharge passage. Theconfiguration of the generator 20 is, therefore, such that onlysatisfactory lather is produced therein.

While there has been shown and described a particular embodiment of thepresent invention, it will be apparent to those skilled in the art thatvarious changes and modifications may be made without departing from theinvention in its broader aspects, and it is, therefore,

time water is discharged through the passageway 38f into the enclosure38 where it is picked up by the bristles 46 thereby producing lather.The lather generated therein is urged to the end ofthe enclosure 38where it enters the channel 42d and from there passes into the dischargechute 55 and out of the housing through the passage 13f. These functionsof the apparatus are performed rapidly so that the user is provided withhot, creamy lather within a matter of a few seconds.

The motor 21 is a shaded pole induction motor having a completelyencapsulated field coil 82. By encapsulating the field coil 82, theswitch 58 and the heater 36 as well as the lead connections betweenthese portions of the apparatus, there is provided a completely safe andsealed electrical circuit which may be immersed in water without anyrisk of shock or electrocution.

Because of the space limitations in the conventional bathroom, thecompact arrangement of the parts in the lather making apparatus 11 isextremely important.

generating assembly 19 immediately below the reservoir assembly 17provides the most efi'icient and compact organization of the elements ofthe apparatus. The

lather generator 20 with its enclosure 38 is designed to f t into thiscompact arrangement with the motor 21 supported at one end thereof andthe valve 48 formed integrally with portions of both the reservoirmember 28 and the enclosure 38. The bottom wall of the enclosure 38 isangled slightly downwardly away from the discharge provided by the framemember 42 so that any water which might accumulate or result from latherremaining in the enclosure 38 when the motor 21 is deenergized will tendto drain to the end of the enclosure remote from the discharge. Thus,when the apparatus is started up again, there will be no tendency forwater rather than lather being discharged through contemplated intheappended claims to cover all such changes and modifications as fallwithin the true spirit and scope of the present invention. a
